ECO 200-810 Principles of
Macroeconomics Homework #6 due 5/4/01
Briefly describe the advantage
and drawbacks to an open vs. closed economy with respect to policy, efficiency
and competition.
Consider the following model economy:
C = 60 + .8Y G = 100
I = 100 T = 0
X-IM = 10
What is the impact of a 10% increase
in G on equilibrium expenditure if the MPM = 0?
What is the impact of a 10% increase
in G on equilibrium expenditure if the MPM = .05?
The tables below describe the domestic
production possibilities of widgets and thingamabobs for Timmyland and
Tangyland (yes, it is the end of the semester and I am not very creative):

What is the opportunity cost of
1 thingamabob in Timmyland? In Tangyland?
Draw the production possibilities
frontiers for each country.
Which country has an absolute advantage
in the production of widgets? In the production of thingamabobs? Which
country has a comparative advantage in the production of widgets?
Suppose the countries specialize
completely in their comparative advantage good and trade with each other.
Timmyland trade ministry offers to trade at the rate of 10 widgets for
20 thingamabobs. With Tangyland accept this trade? Why or why not?
